The century marking the transition from the Middle Ages to the modern era opens with a feudal legacy stemming from the internal divisions of France and England, still embroiled in the Hundred Years' War.Between mutual betrayals and the mystical figure of Joan of Arc, this historical transition marks the arrival of gunpowder in Europe, marking one of the world's epochal changes.Along with it, the invention of movable type printing and the fall of the Eastern Empire pave the wa...

The relationship between the Papacy and power that marked the period of the Avignon Papacy and the conditions that would spark the Hundred Years' War form the backdrop to the events of a French family of Norman origin torn between the concreteness of money and the revolutionary ideas of William of Ockham.These divergent paths were the seeds of future great rivalries between France and England, which began to emerge in the fourteenth century.The middle of the century was domin...

"Once Upon a Time in America" is Sergio Leone's latest film, what the director himself defined as "my cinema".With a very troubled gestation, so much so that it took fifteen years from the first idea to the final realization, and with an overall duration much longer than the normal extension of a cinematographic film, this film turns into a discussion on time, in a way of transposing, with the infinite wisdom of those who know how to mix music and photography, scenography and color,...

The pursuit of the vain hopes of success and the total invisibility of entire segments of the population are the two complementary visions that characterize the protagonists of this novel.Seven stories, separated in places and environments, meet only on a chronological level, leaving each immersed in anonymity, the only possible solution between an unattainable affirmation and a tragedy not consonant with the characteristics of contemporary society.
